Efficacy of brinzolamide ophthalmic suspension 1% for treatment of a vitelliform macular lesion in a patient with desferrioxamine retinopathy.
A 46-year-old woman with a vitelliform macular lesion secondary to desferrioxamine retinal toxicity in the right eye was treated with brinzolamide 1% ophthalmic drops three times a day. A spectral-domain optical coherence tomography (SD-OCT) unit was used to monitor any changes in the macular lesion. Two months after starting the eye drops, the SD-OCT showed a notable improvement in the vitelliform macular lesion's thickness. Six months later, further improvement was noted in the macular lesion thickness on SD-OCT testing in the right eye. Best-corrected visual acuity was initially 1.00 logarithm of the minimum angle of resolution (20/200 on a Snellen acuity chart) in the right eye and 0.14 logarithm of the minimum angle of resolution (20/25(-2)) in the left eye. After 6 months of treatment, visual acuity was 0.92 (20/200(+1)) in the right eye and 0.08 (20/25(+1)) in the left eye. The use of brinzolamide 1% was associated with a marked reduction in a vitelliform macular lesion on SD-OCT testing secondary to desferrioxamine retinal toxicity.
